Question
What chromosomal abnormalities can pre-implantation genetic diagnosis detect?
Answer
Pre-implantation genetic diagnosis, also known as the full name of the third-generation test-tube baby technology, or pre-implantation genetic screening, refers to the process of selecting embryos without genetic diseases before they are implanted into the mother’s body, and then implanting these high-quality embryos into the mother. Typically, pre-implantation genetic diagnosis can carefully examine chromosomes 13, 15, 16, 17, 18, 21, the Y chromosome, and the X chromosome.
